About this network

FSIT is operated by FSIT AG.

What it's used for

• The address space carries hosted services and data center infrastructure, evidenced by netnames CH-FSITAG-20130806 and CH-FSITAG-20160502 registered to FSIT AG IT Operation.
• The AS announces 2048 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, while maintaining 203 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role typical of a data center provider.
• Traffic from this AS consists of web hosting, VPS, dedicated servers, and colocation services for businesses located in Swiss data centers.

Notable

• Registrants for both announced IPv4 prefixes are consistent with the announcer, listing FSIT AG IT Operation and FSIT AG RIPE Admin.
• The address inventory is compact, consisting of two /22 blocks in IPv4 and three distinct /29 or /48 blocks in IPv6, reflecting a focused corporate estate rather than a large residential footprint.
